[QUOTE="Shonver, post: 1169125, member: 34"] I replaced the belt drive on the X axis with a ball screw and NEMA 23 motor. All axes use NEMA 23 motors. I made my own Z axis. Involved getting custom plates laser-cut and the interesting challenge of cutting hardened steel rails and ball screw. The rails and ball screw are case-hardened. I had to use a grinder with metal-cutting disc to get through the hard stuff and I managed to finish the rest on a lathe. [ATTACH type="full" width="1202px"]38614[/ATTACH] [/QUOTE]
